Accidentally deleted Windows.old file incorrectly, now computer will not boot

[DaFrenchster]

So back in December of 2013 my computer was having registry errors that wouldn't allow me to run any applications on it. So I backed everything up and tried to clean reinstall Windows 7. Midway through my reinstallation my computer blue screened. I came back to it the next day and tried again and was successful and a Windows.old file appeared on my C Drive with all of my files and programs in it. I began removing programs and files out of it and then did a stupid thing, I deleted the System 32 folder in the Windows.old file and now my computer will not boot. I have put my Windows 7 disk in to try and install it again but I keep on getting a menu that says

"A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.

Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step."

Please help me

That is because you are running a RAID and you need to reload the RAID drivers during the install process. Go here and get the RAID drivers (under the SATA portion) and copy to a USB drive and load them when asked by Windows.

When I did that none of the drivers would show up unless I unchecked the box that said "Hide drivers that are not compatible with hardware on this computer". I opened up Command Prompt and when I ran Diskpart, Disk List, and List Disk I came up with an error that says "There are no fixed disks to show". But when I tell my computer to start normally you see the Windows 7 logo pop up and it says Starting Windows. I am not sure what that means
